Cuddling 18 MO to sleep - is this bad?

After months of rubbish sleep my DS is finally sleeping through!! (a lot of the time, well 50% anyway)

My little niggle is this. At the moment I cuddle him to sleep then put him down when he is finally asleep. To be honest this is one of my favourite times of day - he is all snuggly and gives me little kisses and talks a bit then is asleep within 15 - 30 minutes.

Has anyone else done this and did their DC finally just go to sleep happily without them in the room? I really don't mind doing this but in practical terms I might have to start getting him to go to sleep on his own (thinking of TTC a second so what happens with a new baby etc).

The few times I have tried to leave the room before he is asleep has resulted in a lot of screaming. Just wondering if I am being a bit selfish about all the pre sleep cuddles. Should I be trying to get him to go to sleep on his own? Or not stress about it?

I do both, cuddle her to sleep and put her down awake, I just go with how she is that night, and she is fine with both. No rod for my back yet and she's 20mths. Do what works for you, there will come a day you wish you could cuddle her to sleep!!

I did this with dd1 from about 14 months, after I stopped bfing her to sleep. can't remember how long it lasted, but at some point it just seemed natural to put her down while awake. I think I patted her to sleep for a while, then at some point I could just leave her to go to sleep. sorry, no real advice other than trust your instincts!
